To PE or Not to PE: Perfusion SPECT/CT Avoids Overdiagnosis.

A 41-year-old woman with metastatic breast cancer presented with dyspnea, hypoxia, and elevated d -dimer. Perfusion planar imaging followed by SPECT/CT of the chest was performed due to the patient's iodinated contrast allergy. Planar images showed multiple pleural-based wedge-shaped defects concerning for bilateral pulmonary embolism (PE).

A call to action; national survey of teaching radiology curriculum to medical students.

Objectives: Radiology and medical imaging are important yet often an underrepresented facet of medical education. Notably, there is concern among radiologists that students do not receive enough radiology exposure and that they struggle to interpret image findings on entering residency. Therefore, this survey aims to identify how medical students perceive the radiology curriculum and to determine gaps in delivery.

Acing the Fundamentals of Radiology: An Online Series for Medical Students and Interns.

Purpose: The current undergraduate radiology education predominantly integrates radiology with other disciplines during preclerkship years and is often taught by nonradiologists. Early exposure to radiology and profound understanding of scientific fundamentals of imaging modalities and techniques are essential for a better understanding and interest in the specialty. Furthermore, the COVID-19 pandemic-related impact on in-person medical education aggravated the need for alternative virtual teaching initiatives to provide essential knowledge to medical students.

Multidisciplinary Approach in Teaching Diagnostic Radiology to Medical Students: The Development, Implementation, and Evaluation of a Virtual Educational Model.

Purpose: The aim of this study was to develop, implement, and evaluate the effectiveness of an online multidisciplinary approach for teaching diagnostic radiology to medical students.

Methods: An online 10-session case-based learning course was designed and taught by a multidisciplinary team of radiologists, surgeons, and internists. Session topics included common clinical case scenarios for different systems and were hosted on a videoconferencing platform.

Intratumoral Metabolic Heterogeneity and Other Quantitative F-FDG PET/CT Parameters for Prognosis Prediction in Esophageal Cancer.

Purpose: To evaluate the impact of intratumoral metabolic heterogeneity (IMH) and other quantitative fluorine 18 (F) fluorodeoxyglucose (FDG) PET/CT parameters for predicting progression-free survival (PFS) and overall survival (OS) in patients with esophageal cancer.

Materials And Methods: In this retrospective study, an automated gradient-based segmentation method was used to assess the maximum standardized uptake value, mean standardized uptake value, metabolic tumor volume (MTV), and IMH index of the primary tumor in patients with biopsy-proven adenocarcinoma or squamous cell carcinoma of the esophagus with an initial staging F-FDG PET/CT. Data were collected between July 2006 and February 2016.
